10. Draw a velocity -time graph and calculate the distance travelled & acceleration of the car in 50 sec.
Velocity (m/s) 5 10 15 20 25 30
Time (sec) 0 10 20 30 40 50

Dear Student,
The graph is as follows: 

The acceleration, a = change in velocitytime taken = 10 - 510 = 510 = 0.5 m/s2
(it can also be calculated using the slope of the given graph, the value is uniform, 0.5m/s2 throughout) 

Calculating total distance using equation of motion, 2 a S = v2 - u2
=> 2*0.5* S = 302 - 52
=> S = 302-522×0.5
=> S = 875m 

Regards
